142368 - Absolutely positioned children in an absolutely positioned table have wrong containing block

Status: RESOLVED DUPLICATE of bug 63895

(Core :: Layout: Tables, defect)

Description

[bora123]

Absolutely positioned Child nodes in an absolutely positioned table must be 
placed relative to the parent node's coordinates, not relative to the client 
area's coordinates. For example, Let say that I want to place a table inside 
another table, both having absolute positions. Parent table is placed on 
left:100 top:100. If I want to place the second table as a child node inside 
the parent table at the coordinate top:10; left:10, the child table must be 
placed in fact onto top:110 left:110.

Confirmed.

Where should the inner table is placed if the outer table has a caption?  That
is, would "top:0" mean "line up with the top of the caption" or "line up with
the top of the first row"?

Both ways are acceptable. I would personally go with top:0. It would be best to 
hear others on this.

Comment 5

[Boris Zbarsky [:bzbarsky]]

um... you did not answer my question, really....  The question was "What is
considered the containing block -- the box that includes the table and captions,
or the box that just includes the table?"

Sorry I should have been more descriptive, I think 

>"top:0" mean "line up with the top of the caption"

is the way to go.

please be aware that captions in abs. pos tables have a problem: bug 84715
